Description

Technical Field

[0001] This utility model relates to the field of drinking water treatment technology, specifically to a disinfection device for decentralized water sources in rural areas. Background Technology

[0002] In rural areas, water sources are mostly found in the form of wells, streams, or ponds, and are scattered and sparsely distributed, making centralized management and monitoring difficult. This hinders the installation of standardized disinfection equipment or systems. Furthermore, traditional centralized disinfection systems require extensive infrastructure construction, including pipeline laying and power supply, which is prohibitively costly and uneconomical for rural areas. Daily maintenance and troubleshooting also require specialized technicians, and the limited technical support in rural areas results in poor long-term reliability of the equipment. For these reasons, most rural water sources are used directly for daily life without effective disinfection, significantly increasing the risk of water pollution and disease transmission.

[0003] Therefore, this solution provides a highly efficient disinfection device suitable for scattered water sources in rural areas, enabling effective disinfection and management of water sources and ensuring the drinking water safety of rural residents. Utility Model Content

[0004] The present invention aims to provide a disinfection device for decentralized water sources in rural areas to solve the problem of inconvenience in disinfecting decentralized water sources in rural areas.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rural decentralized water source disinfection device, comprising a box body, with an inlet and an outlet on the left and right sides respectively; a first disinfection chamber and a second disinfection chamber are provided inside the box body, with a partition plate between them and a connecting notch at the top of the partition plate; the inlet is connected to the first disinfection chamber, and the outlet is connected to the second disinfection chamber; rectangular baffles are arranged alternately in the first disinfection chamber, the baffles are hollow inside and have several through holes on the side facing the inlet; air guide pipes are provided on the upper and lower side walls of the first disinfection chamber, the air guide pipes are connected to the inside of the baffles, and an ozone generator is connected to the outside of the air guide pipes; an electrolytic electrode is installed in the second disinfection chamber, and a microcurrent generator is installed on the outside of the box body, with the electrolytic electrode and the microcurrent generator electrically connected.

[0006] The principle and advantages of this scheme are:

[0007] 1. In practical application, the ozone generator in the first disinfection chamber injects ozone into the baffle plate through a gas duct and releases it into the water through through-holes, forming evenly distributed ozone bubbles that quickly and effectively kill most bacteria and viruses in the water, achieving preliminary disinfection. The second disinfection chamber uses electrolytic electrodes and a microcurrent generator to produce sodium hypochlorite or other strong oxidants to further remove residual microorganisms and organic pollutants, ensuring that the effluent water quality meets drinking water standards. This dual disinfection mechanism effectively guarantees the disinfection effect of the water source, protects the drinking water safety of rural residents, and neither of these disinfection methods produces additional chemical substances, avoiding secondary pollution and meeting environmental protection requirements.

[0008] 2. This solution combines two disinfection methods. Ozone disinfection can rapidly kill most bacteria and viruses in the water, preventing their reproduction and effectively applicable to various water sources in rural areas, such as well water, streams, and ponds. On the other hand, the hypochlorous acid and hydroxide ions generated by micro-current electrolysis can continuously exist in the water, providing ongoing disinfection and ensuring long-term water quality stability. This is particularly important for scattered water sources in rural areas where frequent maintenance and monitoring are lacking. Furthermore, the partition plates separate the water in the two disinfection chambers, preventing the mixing of water with different disinfection levels and thus avoiding a reduction in the final effluent disinfection effect.

[0009] 3. The staggered baffles arranged vertically within the first disinfection chamber of this scheme not only increase the disinfection time of the water in the first disinfection chamber, but also make the water flow path more tortuous, increasing the degree of disturbance within the water and resulting in more uniform mixing with ozone. On the other hand, since ozone has low solubility in water and decomposes rapidly into oxygen, leading to poor disinfection effect, this scheme has through holes for ozone to pass through on each baffle, and ozone is transported by a gas guide pipe. That is, the water undergoes ozone disinfection once when it flows through each baffle, which fully ensures the disinfection effect. It also eliminates the need for a separate stirring structure and power source to ensure sufficient mixing of ozone and water, reducing the overall structural complexity and manufacturing cost of the device.

[0010] 4. The entire disinfection device has a compact structure and occupies little space, making it suitable for installation at scattered water sources in rural areas. Furthermore, components such as the ozone generator, electrolysis electrode, and microcurrent generator can be replaced and maintained independently, reducing maintenance costs and complexity.

[0011] 5. Both ozone disinfection and microcurrent electrolysis disinfection in this solution are low-energy technologies that do not require a large power supply. Compared with traditional centralized disinfection systems, this solution also does not require the laying of a large number of pipelines, reducing the initial construction cost and making it suitable for rural areas with limited funds.

[0012] Furthermore, the size of the flow channel between the baffle and the side wall of the box is 10-20cm.

[0013] The aforementioned limitation on the flow channel is intended to: 1) ensure the water flow velocity and continuity; too small a range would prevent continuous disinfection at each baffle, while too large a range would result in excessively fast water flow and insufficient disinfection reaction between the water and ozone; and 2) break the laminar flow state by changing the path, creating turbulent flow and allowing ozone gas to be more evenly dispersed in the water, thereby improving the disinfection effect.

[0014] Furthermore, the spacing between two adjacent baffles is equal, ranging from 15 to 30 cm.

[0015] The aforementioned spacing effectively ensures that ozone gas can diffuse evenly within the spacing area, thus fully disinfecting the water. If the spacing is too small, the flow resistance of the water will increase, increasing energy consumption. If the spacing is too large, there will be too much water in a single spacing and too little ozone, making it impossible to carry out comprehensive disinfection and resulting in inadequate disinfection of local water bodies.

[0016] Furthermore, a protective filter membrane is provided at the through holes of the baffle plate, and the protective filter membrane is made of a hydrophobic material.

[0017] The protective filter membrane can prevent residual impurities in the water from entering the baffle plate and avoid clogging the pores; at the same time, the hydrophobic material can effectively prevent water from entering the baffle plate, keeping the inside of the baffle plate dry and preventing ozone from decomposing prematurely due to moisture, thus reducing the disinfection effect.

[0018] Furthermore, the anode electrode of the electrolytic electrode has a mesh structure, and the cathode electrode has a sheet structure.

[0019] The mesh-structured anode electrode effectively increases the contact area between the electrode and water, meaning it has more active sites, which can generate more oxidant and improve disinfection efficiency. Meanwhile, the sheet-shaped cathode electrode can provide a more uniform current distribution, avoiding excessive local current that could lead to overheating. This helps to improve hydrogen generation efficiency while reducing the occurrence of side reactions.

[0020] Furthermore, the anode electrode of the electrolytic electrode is a ruthenium-titanium anode, and the cathode electrode is a stainless steel cathode.

[0021] Ruthenium-titanium anodes exhibit excellent electrocatalytic performance, enabling them to efficiently generate oxidants, while stainless steel cathodes can stably generate hydrogen during electrolysis, reducing side reactions and thus improving electrolysis efficiency. In addition, both ruthenium-titanium anodes and stainless steel cathodes have good corrosion resistance, maintaining stable performance in strong oxidizing environments and reducing maintenance costs.

[0022] Furthermore, a filter screen is provided at the water inlet. The filter screen is double-layered, with the first layer having a pore size of 50-100μm and the second layer having a pore size of 20-50μm.

[0023] The pore size of the double-layer filter screen decreases sequentially, which can effectively filter and intercept impurities of different sizes in the water, ensuring water clarity. Clear water quality can reduce the consumption of disinfectants and improve the disinfection effect.

[0024] Furthermore, the first disinfection chamber has a sedimentation tank formed by a downward protrusion at the bottom of the filter screen. The sedimentation tank has a trapezoidal cross-section and a drain outlet at the bottom.

[0025] Furthermore, the bottom of the box is equipped with casters. Attached Figure Description

[0026] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0027] The following detailed description illustrates the specific implementation method:

[0028] The reference numerals in the accompanying drawings include: 1. Box body; 2. Roller; 3. Inlet; 4. Outlet; 5. First disinfection chamber; 6. Second disinfection chamber; 7. Baffle plate; 8. Through hole; 9. Air duct; 10. Ozone generator; 11. Divider plate; 12. Connecting notch; 13. Electrolysis electrode; 14. Microcurrent generator; 15. Filter screen; 16. Sedimentation tank.

[0029] The basic implementation examples are as follows: Figure 1 As shown: A rural decentralized water source disinfection device includes a housing 1. The bottom of the housing 1 is equipped with rollers 2 for easy transfer or handling of the disinfection device. The housing 1 has an inlet 3 and an outlet 4 on its left and right sides, respectively, both located at the bottom of the housing 1. The housing 1 contains a first disinfection chamber 5 and a second disinfection chamber 6, separated by a partition plate 11 with a connecting notch 12 at the top. The inlet 3 connects to the first disinfection chamber 5, and the outlet 4 connects to the second disinfection chamber 6.

[0030] The first disinfection chamber 5 has vertically arranged rectangular baffles 7 arranged in an alternating pattern. The baffles 7 are hollow inside and have several through holes 8 on the side facing the water inlet 3. The upper and lower side walls of the first disinfection chamber 5 are provided with air guide pipes 9, which are connected to the inside of the baffles 7. An ozone generator 10 is provided on the outside of the box 1, and the air guide pipes 9 are connected to the ozone generator 10.

[0031] The gap between the baffle plate 7 and the side wall of the tank 1 has a flow channel size of 10-20cm. This serves two purposes: first, to ensure the water flow velocity and continuity; and second, to break the laminar flow by changing the path, creating turbulent flow and allowing ozone gas to be more evenly dispersed in the water, thus improving the disinfection effect. The interval between adjacent baffle plates 7 is equal, ranging from 15-30cm. This interval effectively ensures that ozone gas can diffuse evenly within the interval area, fully disinfecting the water. In this embodiment, the gap between the baffle plate 7 and the side wall of the tank 1 has a flow channel size of 15cm, and the interval between adjacent baffle plates 7 is equal, ranging from 25cm.

[0032] Preferably, a protective filter membrane (not shown in the figure) is provided at the through hole 8 of the baffle plate 7. The protective filter membrane is made of a hydrophobic material. The protective filter membrane can prevent residual impurities in the water from entering the interior of the baffle plate 7 and avoid clogging the through hole 8. At the same time, the hydrophobic material can effectively prevent water from entering the interior of the baffle plate 7, keep the interior of the baffle plate 7 dry, and avoid premature decomposition of ozone due to moisture, which would reduce the disinfection effect.

[0033] Electrolytic electrodes 13 are installed in the second disinfection chamber 6. In this embodiment, there are 3 pairs of electrodes, which can be increased or decreased according to actual needs. A microcurrent generator 14 is installed at the bottom of the outer side of the chamber 1. The anode electrode of the electrolytic electrode 13 is connected to the positive terminal of the microcurrent generator 14, and the cathode electrode of the electrolytic electrode 13 is connected to the negative terminal of the microcurrent generator 14. The anode electrode of the electrolytic electrode 13 is a ruthenium-titanium anode, and the cathode electrode is a stainless steel cathode. The ruthenium-titanium anode has excellent electrocatalytic performance and can efficiently generate oxidants, while the stainless steel cathode can stably generate hydrogen during electrolysis, reducing the occurrence of side reactions and thus improving electrolysis efficiency. In addition, both the ruthenium-titanium anode and the stainless steel cathode have good corrosion resistance and can maintain stable performance in strong oxidizing environments, reducing maintenance costs. Preferably, the anode electrode of the electrolysis electrode 13 has a mesh structure, and the cathode electrode has a sheet structure. The mesh structure of the anode electrode effectively increases the contact area between the electrode and water, that is, it has more active sites, which can generate more oxidant and improve the disinfection efficiency. The sheet-shaped cathode electrode can provide a more uniform current distribution, avoid excessive local current and overheating, help improve the hydrogen generation efficiency, and reduce the occurrence of side reactions.

[0034] This design also includes a filter screen 15 at the water inlet 3. The filter screen 15 is double-layered, with the first layer having a pore size of 50-100μm and the second layer having a pore size of 20-50μm. The double-layered filter screen 15 can effectively filter and intercept impurities of different sizes in the water, ensuring water clarity, reducing the consumption of subsequent disinfectants, and improving the disinfection effect. The first disinfection chamber 5 protrudes downwards at the bottom of the filter screen 15 to form a sedimentation tank 16. The sedimentation tank 16 has a trapezoidal cross-section and a drain outlet at the bottom, facilitating the settling of filtered impurities and sludge into the sedimentation tank 16 for regular cleaning.

[0035] In practice, the water to be disinfected enters the first disinfection chamber 5 through the inlet 3. The ozone generator 10 injects ozone into the baffle plate 7 through the air pipe 9 and releases it into the water through the through hole 8, forming evenly distributed ozone bubbles. The ozone quickly and effectively kills most of the bacteria and viruses in the water, achieving preliminary disinfection. The second disinfection chamber 6 generates sodium hypochlorite or other strong oxidants through the electrolytic electrode 13 and the microcurrent generator 14 to further remove residual microorganisms and organic pollutants, ensuring that the effluent water quality meets drinking standards. This effectively guarantees the disinfection effect of the water source and protects the drinking water safety of rural residents.
